Title: Light amplifying transmission system
Inventor: EDAKAWA NOBORU
IPC: H04B10/2513
Filed: 1994-09-12
Abstract: PURPOSE: To increase system margin in an optical fiber transmission system using an optical soliton as a base and to obtain a practical several 10s Gbit/s long distance large capacity light amplifying transmission system by executing RZ optical signal transmission by adopting many transmitting optical fibers whose zero dispersion wavelength is intentionally longer than signal wavelength. CONSTITUTION: The transmission system is constituted so that the average zero dispersion wavelength of a transmitting optical fiber is shorter than the wavelength of signal light, the zero dispersion wavelength of a transmitting optical fiber corresponding to >=1/3 and <=2/3 the whole length is longer than the wavelength of an optical signal and the absolute value of the wavelength dispersion is larger than a half of the absolute value of the average wavelength dispersion value of the whole length of the optical fiber. For instance, the wavelength dispersion value of the transmitting optical fiber in the wavelength of the optical signal is about-0.6ps/nm/km in a transmitting optical fiber 4, about 1.2ps/nm/km in a transmitting optical fiber 5 and about 0ps/nm/ km in a transmitting optical fiber 6.  A positive value for the wavelength dispersion value indicates that the zero dispersion length of the optical fiber is shorter than the wavelength of the optical signal and a negative value indicates that the zero dispersion wavelength is longer.

Title: Hot water heater for ornamental fish
Inventor: TSUKIDA KAZUSANE
IPC: H05B3/00
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal rise in the temperature of a heater by providing an abnormal temperature detection means electrically connected in parallel to a heating wire of the heater and a current cutting means on a power source line of the heating wire. SOLUTION: A heating wire 405 and an abnormal temperature detection means 406 connected in parallel to the heating wire 405 are arranged in a heater body 401. A current cutting means 407 comprising a current fuse is interposed in one electric wire 403. The heater body 401 is designed to attain a temperature of 150 deg.C, for instance, under water. Now when the heater body 401 is not set under water, the heater body 401 fails to radiate heat, inevitably causing an abnormal temperature exceeding 150 deg.C. If the set detection temperature of the abnormal temperature detection means 406 is set at 200 deg.C or 300 deg.C, for instance, the temperature is detected by the abnormal temperature detection means 406 and a short-circuiting occurs at both ends of the heating wire 405 to let an overcurrent flow.  As a result, the fuse of the current cutting means 407 burns out to cut the current to the heating wire 405, thereby preventing the generation of abnormal heat in the heater body 401.

Abstract: PURPOSE:To eliminate the round of an abnormal address by storing an idle address and a write address in more than three memories, selecting the address commanding a majority among the addresses and giving them to a data memory or previously correcting the errors of the write/idle addresses so as to set them to be the addresses. CONSTITUTION:The write addresses from a write address generation means 2 are written in common into more than three memories 311-31n in a read address generation means 3 as the read addresses of the data memory 1.

IPC: G06T13/20
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a determination board for an inter-polygon distance for the system by allowing shortest feature term algorithm to use a Voronoi plane and its area. SOLUTION: Two feature terms are selected (S300). In the beginning, the feature terms can be selected at random. Then a test is conducted to confirm whether or not the shortest points between the two feature terms are present in Voronoi regions of other feature terms (S305). Then the system confirms which feature is transmitted (S307). When not, the direction where both the Voronoi planes are infringed, namely, the shortest points relates the Voronoi planes (S310). Then the feature terms corresponding to the infringed Voronoi plane are selected as new feature terms for matching (S315). In this case, the process is looped until the shortest feature term is found. Consequently, a defect for determining a collision between polygons can be overcome.

Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To prevent an unstable state of a control and implement good drivability, even if a feedback control is executed at the time of transition in a fuel priority type engine. SOLUTION: In an actual equivalent ratio calculation means 19 in cylinders, an actual equivalent ratio in cylinders FAIcl is calculated based on an absorbed air amount in cylinders and an inflow fuel injection amount in the cylinders. In a control deviation calculation means 21, control deviation e of which target equivalent ratio is the actual equivalent ratio in cylinders FAIcl is calculated from a difference between the actual equivalent ratio in cylinders FAIcl and an exhaust equivalent ratio FAIex that is calculated based on an exhaust air- fuel ratio obtained by an air-fuel ratio sensor 6. In a controller 22, feedback control of a fuel injection amount of an injector 4 is executed so that the control deviation e converges at zero.  Since the control deviation e is calculated from the difference between the actual equivalent ratio in cylinders FAIcl and an exhaust equivalent ratio FAIex, the air-fuel ratio feedback control can be executed in a good follow-up property at the time of transition.
